It was Boston's second victory over Sacramento in eight days, and the Celtics' fourth win in five games overall.

As happy as he was with the comeback, Irving said it doesn't compare to the mentality Boston will need in the postseason to be successful.

"It's going to be a dogfight, no matter who you are playing against," Irving said. "Obviously, when you have a team fighting for playoff position, it is going to be that type of intensity and you have to be ready for it."

The Kings have dropped 13 of 17 road games as their hopes of catching the Clippers for the Western Conference's final playoff spot took another hit.

"Still believe we have a chance to make the playoffs," Hield said. "We suck right now. We have to close out games better and I don't know if it's the pressure or something else."

Sacramento had split the first two games of its four-game trip. The Kings were hoping for a boost with rookie Marvin Bagley III returning after spraining his left knee in a home loss to Milwaukee on Feb. 27 and missing five games.

He played only 10 minutes in the first half but had 10 points to help the Kings build a 17-point lead. He finished with 14 points and six rebounds.

The Celtics returned home on the mend following a 3-1 West Coast trip.

Jayson Tatum was back in the starting lineup after missing a game with right shoulder soreness. Smart was battling a cold but also started. Meanwhile, Terry Rozier and Daniel Theis both sat out with illnesses.

It had its effect. Despite playing on two days' rest, the Celtics were slow on switches on defense and relied on jump shots early. They stayed close thanks in large part to Irving's 19 first-half points.

Boston was much more energetic in the third quarter, opening on a 9-2 run to take its first lead since early in the first quarter.

Sacramento led 89-79 with less than three minutes to play in the period before a 3 by Irving and three straight 3-pointers by Brown put the Celtics back in front.

Boston led by as many as 13 in the fourth quarter.
